[solved]How to load data from store to FormPanel?

I have a form.Panel in which I show some data. I receive the data as XML from the server and load it directly into the fields using

podform.getForm().load({url:url_servlet+'kadastr_zemform.jsp' ... along with a XMLReader.
Now I want to show the data in 3 separate form.Panel. But I just wan't to load the data once before loading it into panels. I guess form.load() no longer works for me in that case.
How would I load the data into several panels? Should I use a store cause I also need to be able to edit the data and send it back?
